| ## BERT-based Text Classification Model |
| This model is a fine-tuned version of the bert-base-uncased model, specifically adapted for text classification across a diverse set of categories. The model has been trained on a dataset collected from multiple sources, including the News Category Dataset on Kaggle and various other websites. |
|
|
| The model classifies text into one of the following 12 categories: |
|
|
| * Food |
| * Videogames & Shows |
| * Kids and fun |
| * Homestyle |
| * Travel |
| * Health |
| * Charity |
| * Electronics & Technology |
| * Sports |
| * Cultural & Music |
| * Education |
| * Convenience |
| The model has demonstrated robust performance with an accuracy of 0.721459, F1 score of 0.659451, precision of 0.707620, and recall of 0.635155. |
|
|
| ## Model Architecture |
| The model leverages the BertForSequenceClassification architecture, It has been fine-tuned on the aforementioned dataset, with the following key configuration parameters: |
|
|
| * Hidden size: 768 |
| * Number of attention heads: 12 |
| * Number of hidden layers: 12 |
| * Max position embeddings: 512 |
| * Type vocab size: 2 |
| * Vocab size: 30522 |
| * The model uses the GELU activation function in its hidden layers and applies dropout with a probability of 0.1 to the attention probabilities to prevent overfitting. |

| ## Example |
|
|
| ```from transformers import AutoModelForSequenceClassification, TFAutoModelForSequenceClassification``` |
|
|
| ```from transformers import AutoTokenizer``` |
|
|
| ```import numpy as np``` |
|
|
| ```from scipy.special import expit``` |
|
|
| |
| ```MODEL = f"PavanDeepak/Topic_Classification"``` |
| ```tokenizer = AutoTokenizer.from_pretrained(MODEL)``` |
| |
| ```model = AutoModelForSequenceClassification.from_pretrained(MODEL)``` |
| ```class_mapping = model.config.id2label``` |
|
|
| ```text = "I love chicken manchuria"``` |
| ```tokens = tokenizer(text, return_tensors='pt')``` |
| ```output = model(**tokens)``` |
|
|
| ```scores = output[0][0].detach().numpy()``` |
| ```scores = expit(scores)``` |
| ```predictions = (scores >= 0.5) * 1``` |
|
|
|
|
| ```for i in range(len(predictions)):``` |
|
|
| ```if predictions[i]:``` |
| |
| ```print(class_mapping[i])``` |
| |
| ## Output: |
|
|
| * Food |
| * Videogames & Shows |
| * Homestyle |
| * Travel |
| * Health |
